B-e'it known that I, EARL D. .YALnnoN, a citizen of the UnitedStates, residing F01- 0111, inithe county of Sacramento and State if'Ca lifornia have invented a new and useful ,pre'vn' iate m vh tioriinfsuch id clear terms aswill enable those skilled}; ,the'art to construct anduse e am This'inventipn relates to a" governor used 1 gas; r explosive engines for the purpose .of automa 'call p advancing .and-.retarding ..th'e'.' -s"ar lwhich explodes the gases in the lin er o'f tlieengine. i It is a cofmmon practice to-use a hand opated mechanism to advance and retard the in automobiles to regulate the speed U n ine,-but this practice has the disan'tagei that should the user of the m'ac ine to place the spark lever at the roper'pon'it when the engine is to be started e villi-be liable to be seriously injured by U the engine exploding the charge of gas at the 25 avrong time with. respect to the place at which it should explode ,to turn the engine ,in the accustomed manner, the result being "that the engine crank is violently'thrcm'n in the reverse direction so quickly that it will 3 break the arm of the person trying to start ":the engine. This defect is sought to be avoided in this invention and at the same time means is provided to make it possible {to retard or accelerate thie effect of the auto- 3 matic device as may be iecessary. With this invention it is im )ossible for the .personrunning spark in the advanced position for thegov ernor will at once return the sJark to the 4Q tlatef position when the engine as stopped, thus making it possible to start the engine :3 atfiny tiinc without danger of a premature r ex' lojslon. n'the drawings in which the same numeral figures, Figure 1. is a vertical elevation of the regulato'r showing its mode of attachment to 1'. the cam shaft of a gas engine, Fig. 2 is asecitional View showing the inside of the circuit SQ'Z'Cldser box, Fig. 3 is a sectional view showing the bearings of the circuit closer box on its shaft,-and Figs. 4, 5, 6 and 7 are details of gfifirious small parts of the invention.

! driven from the camshaft 1 which has a g bevel gear? in mesh with a second bevel gear 3 carried by the governor shaft 4, said shaft at being journaled in boxes 5 and 6. The shaft lhas a collar 7 which keeps the circuit closer box 8 in its proper place. Above the circuit closer box is placed the governor 9., The governor may be of'any type, that shown being of the common two ball type, the clamps 10 holding it from E moving at the upper end and the ring 11 moving at the lower endas the arms of the 1 governor balls move outwardly. A ring l2 "on the shaft 4 prevents the governor from rising too high, and heavy springs 13 are. attached to; the balls to make it certain. that they will be properly fretracted when the peed'of, the engine runs down. The ring ,1 l. h as a groove around it and a forked lever 13 takes in the groove to move the bell crank about the agis- 14 its other lever 15 being securedto one end of the link 16 by any suitable means, nreferably by a ball and socket joint. This link 16 is connected with the circuit closer box by means of an arm 17.

The circuit closer is loosely hung on the governor shaft 4 ball bearings 18 being provided to make it have as little friction on the shaft as is possible. I Means to lubricate the ball bearing of the circuit closer box is shown at 19. The circuit closer box is simply a ring having a hub that fits the governor Shaft closely at the ball bearings and which has four holes bored through it. In each of the holes there is placed a short tube 20, said tube having a collar 21 and having its outer end threaded to receive the lock nut 22. This lock nut holds the small tube in place, and over the projecting end of the tube is screwed the cap 23 said cap i having the terminal 24. The inner end .of I the small tube 20 has a slot 25 cut in it to thold the small roller pin 26 in its proper p osition. This small roller pin 26 carries the roller 27 and it has the pin 28 from it at right .angles with its ength to i i make certain that the roller will at all times i be held in the proper position with relation to the rin of ii er 29 so that the rollers will i Wear even y and so they will not cause undue 105 i friction. The in 26 is pressed down on the y means of asmall "spiral l spring 31 inside the tube2'0. The fiber roll lhas a small metal piece 30 inserted in its {periphery and connected with the shaft in rojec'ting governor under manual control as well as' under automatic. control the rod 32 extends a to such a-point as may be in the reach of the person driving the machinewhere it is connected with the lever 33. This lever has a scale 34: under it to show the driver the position of the spark with respect to the dead center, and when it may be wished to accelerate the spark or to retard it independent of the action of the, engine it may be easily done by simply pressing on thelever 33 in the desired direction, since it will then act to compress or ex and the governor as the case may be. The ever 33 simply moves .across the scale 34 as the governor rises or falls there being means to secure it in any fixed position.

The operation of the regulator is as fol-' lows: The machine being sto )ped the person' who wishes to start it maltes the proper engine connections and turns the crank of the engine the circuit closer box always holding the spark in the slow position at the time the engine is to be started. As the speed is increased the governor opens and t e s ark is advanced to such'a point as may e necessary for that speed, or should the engine be stopped, or have its fuel supply turned off the circuit closer is automatically 1 turned back to the retarded position where there is no danger of backfiring when the engine is started.

Having thus described my inyention what i I claim as new and desire to secure by Letters Patent of the United States is as follows, modifications within the scope of the appended claim being expressl reserved.

In a s ark timer, the combination with a driven-s iaft of a gas engine, a-circuit closing box carried on ball bearings on said shaft, said circuit closingbox having a series of plugs carrying slotted pins, rollers in the slots of said pins, a pin passing through the slotted pin and a guide for keeping the slotted in from rotating, a governor carried by the s iaft, an arm secured to the governor and to the circuit closing box and adapted to advance the spark as 'the speed of the engine increases, and manual meana for advancing and retarding the spark :H the will of the driver.

In testimony whereof I have hereunto set my hand this 2nd day of November, 1907, in the presence of the two subscribed witnesses.
